I have my .pro file, Sample.pro, and I have other .pro files included by Sample.pro using "include(OtherSample.pro)".

When I create a new file class in QtCreator, By default the file is added to one of the OtherSample.pro files.

I can not find out the reason why these files are adding to OtherSample.pro file.

Can anyone in the forum have any Ideas about this?
Thank you.
